Air flow meter is used to measure the flow of air or water through a tube. Automobiles use air flow meter to measure atmosphere quantity entering the engine at a time and to ensure smooth functioning of the engine. Air flow meters have various important functions some of which are listed less than. Speed Regulation of Air Flow: They're used to regulate the flow of air or gas present in the tube and to measure the speed of the flow. To Compute Consumption: These equipments works extremely well to measure the gas consumption on the inside tube apart by way of the rate of flow of gas the particular tube. To Guide the Drivers: The air flow meters are usually connected to the computers, which indicate normal readings. We've passed away of an abnormal rise or dip in the flow or during equipment malfunctions, warning lighting is flashed to alert the drivers. The meters also give vital information about the functions of the engines. It Serves as a Regulator: Digital piace of cake meter equipment may possibly used as to control the flow of air through the adjustments of the valves. As air flow meter plays a vital role in regulating the flow of air and the functions of the engine, it is crucial that these equipments in order to maintained properly. Here are some tips on the way to diagnose a faulty air flow meter. Check Engine Light: One of the earliest symptoms of a faulty mass air flow meter (MAF) will be the flashing light on the check engine light on the instrument panel. This warning light could be triggered due in order to functions and to find out whether it includes any problems on the mass air flow meter, the cars computer has staying analyzed carefully. A reputable mechanic can get united states computer analyzed. Car owners too can do it using are just looking for auto diagnostics scanner, which is included in any auto spare part stores. If your scanner codes refer to a malfunctioning MAF, the MAF end up being replaced. Low Performance for this Engine: As the MAF is responsible to maintain a proper balance of air and fuel within engine, any failure in this gadget can result within a range of exhaust problems including low gas mileage, stalling or knocking and others. Measure the Hot Wire MAF Sensor's Output Voltage. Typically a voltmeter coupled to the MAF sensor should read around two.5 volts. Raise the rpm of the engine and take the voltmeter readings. You must pick one register a steady increase in the reading corresponding for the throttle opening. If the voltage readings are erroneous, that would mean that the sensor is not producing signals. Check the Self-cleaning Circuit Relay on MAF Sensor. The self cleaning circuit cleans the MAF wire. If the relay that regulates the current into the circuit is broken, then the computer will be not able to clean the cable. The dirt and other debris could leave the sensor faulty. Once the involving the MAF malfunction is identified, it must be rectified immediately to restore the normal functioning of the piece of cake meter.
